I’ve owned my Critical Mass Reactor for more than 10 years. The performance has been exceptional. These watches are gorilla proof. Wore out the original rubber band & replaced the battery twice. Thanks to the superlative factory refurbishment my watch still looks great in a dress or sports application. Reactors Customer Service is the best !! Highly recommend Reactor Watches.
